This document discusses verbals, which are verb forms used as nouns, adjectives, or adverbs rather than as verbs. There are three types of verbals: infinitives, which use "to" and can function as nouns, adjectives, or adverbs; participles, which end in "-ing" or "-ed" and are used as adjectives; and gerunds, which end in "-ing" and function as nouns. The document provides examples and exercises to help distinguish between verbs and verbals based on how they are used in sentences. It emphasizes that identifying verbals is important for understanding sentence structure.
